Turbo'd Locost Kit Car - chasing 300bhp!

[slickcell]

More bits arrived throughout the week.

I bought some CNC plates specific to the Haynes roadster and some lathed bush tubes etc so making them should just be a case of slotting them into the jig and welding up.

 

[slickcell]

We got loads done today:

Rear roll bar fitted

Wishbones done

Secured roughly in place with some wire to check how they look

 

[slickcell]

Still picking up some bits as I go along:

OMP Flat bottom wheel

OMP 4 point harnesses

Aluminium fuel tank

MK Indy dash panel

Bonnet

Oh and my engine crane arrived, so we offered up the engine to see what room there was for a turbo - LOADS!

And the English axle has just arrived to replace the Atlas axle I was going to go with originally. Much better shout this as it comes complete, with brakes etc too.

The one photographed above is an atlas, an English is front loading.

Maybe you intended to upload the pic of the Atlas.

Seriously? Lol, I bought it on the understanding that it was an English! If only I knew what I was on about lol. On the plus side, I paid £120 for it so that must be an absolute bargain!

 

[PaulYDP]

Yeah that's not an English axle, the diff in an English axle is bolted on to the front. It could be any number of atlas axles or it could be a Koln, if it's a koln then you'll struggle to find an LSD for it. If you put up a picture of the diff mounting side then it'll be easier to identify.

Yep that's 100% an Atlas axle! do you know what ratio it is?

English - the main casing is formed steel not cast, just the pigs head is Cast. and the bolts are too the front (front loading)

Ahhh.....haha, oh well I have it now. It means I can push more powwaaa lol

If you want to identify exactly what you've got this might help - What Is The Difference....Atlas & Baby Atlas?

Mine is 52" end to end

How do I identify what ratio it is? I was told it was 3:7 but not sure if be confident of this now

sounds like you were told a lot of things! refund?

No.....as long as its an atlas, I'm happy enough. The CWP and whatever else, I can change going forward. I can't delay it any longer trying to find a replacement axle. If its atlas, I don't have to worry about it bending even with big big power. If its a koln, I'll be getting a refund.

Its a 52" full Width Atlas axle, the drain plug gives it away & diff cover is rounded.

To Check ratio - You can see how much one rotation on the input rotates the wheel flange, or you can pull the diff down and divide the Crown wheel teeth by the Pinion tooth number.

On Sierra diffs there are some stampings on the casings to tell but at this stage who's to say it hasn't been altered. 3.75:1 is a popular ratio and was installed in lots of models.

Are you staying on rear drums? if your going discs you will need to have the hubs lathed down or the discs opened up by a few MM.

Thanks mate. I'll check the ratio when I get back from Rome on Saturday. I'm staying with drums for now. I'll fit a set of wilwood brakes up front and see how it responds from there. If I need/want to upgrade the rears thereafter, I will do

There is very little need for the rear braking.

The only major advantage on a 7 would be getting rid of the weight of the drums, cylinders & shoes for a nice alloy calliper and lightweight disc.

Are the conversations not pretty expensive though? I'll probably go that way but will stick with the drums on the rear for now.

Not if you go with the handbrake Sierra Calipers,

I actually have a pair of Weld on mounts for sierra calipers on atlas axle and Lightweight discs to suit in the garage if you are interested!

Would take £75 for the Discs and Mounts

Let me think about it!

So based on the advice of turning the flange and counting the rotations, I believe I had a 3.44 ratio differential. Not sure how that will feel but we will see when on the road!

Another productive weekend at the car, although it doesn't look like much......got the wishbone brackets on and squared up with the aid of a jig.

Also slotted the axle in to see how it would look

I then removed all four of the original axle brackets - they were well on!!

So it's cleaned up and ready to take the new brackets.

I also picked up a nice floor mounted pedal box kit with remote bias adjuster and braided brake lines....

This is something I know absolutely nothing about, but it seems pretty epic. I'll be keeping an eye on the build, it looks a cracker!

 

[slickcell]

Some bodywork arrived over the past few days and I fired it on for ****s and giggles....
